Please leave the stupid comments to the others... there are too many of them already. When not sure, attempt to find the answer yourself before blurting out something that is not true, misdirecting, or not constructive.
While we're on the subject of compounding stats...
A sack is also a solo tackle
.5 sack is an assist
Interceptions are also Passes Defensed
Stripping a ball carrier is also a solo
Stripping a QB behind the LOS is a solo tackle, sack, and forced fumble
If the QB is scrambling and you strip him, TFL replaces sack.
Why would GLB change stats and go by anything else?
ALSO, THOSE DAMNED 'UNABLE TO SECURE THE BALL DUE TO NEARBY DEFENSE' PLAYS ARE DROPS! STOP TRYING TO OBSCURE THE DROP NUMBERS!
